To all whom it may concern: of securing the pivot pin to the tongue,Fig. Y Be it known that I, HENRY OSHEA, a citi- 9 showing the pinpivoted in the tongue while zen of the United States, residing at Johns-Fig. 10 shows the tongue and pin integral. town, county of Cambria,State of Pennsyl- These last two iigures also illustrate different 5Vania, have invented a new and useful Imforms of recess R. 55

Tosaid tongue is secured at one end the pin 1o My invention relates tothat form of switch p upon which it turns, the boss B furnishing 6owhich has a movable tongue or point hinged abearng for it. The end ofthe tongue is upon a pin near one end.

By 9obodying my invention. Fig. 2 is a top view track surface I mean asurface performing of the head end of the Sallie. Fig. 3 is a secthesame function as the head of the rail, that tion on line o o. and Fig. 4is a section on is, a surface which supports the tread of the line b-b.Fig. 5 is a top view of a switch wheel as it rolls along the track. Werethe 45 similar to Fig. 2 but having different style plate O to lie hereso that the wheel traveled 95 of plate C. Fig. 6 is an end view of theswitch over it, the action of the wheel would tend to from the line c-c.Fig. 7 is a vertical secloosen and wear and so greatly destroy the tionon line b-b. Fig. S'shows a section on efficiency of the plate. Itherefore construct line a-a of a switch composed of rolled steel theplate so that it only occupies a portion 5o rails R R. Figs.9and 10illustrate methods of the place behind the tongue, and I form 1o.b

The method of applying this device is as 5 follows: The tongue T havingbeen placed in position and the nut N being in its pocket the plate C isput in place with the lug Z entering the recess R in the tongue, thebolt d is inserted in nut N and the whole clamped 1o together. Insteadof the lug Z entering a recess as shown in Fig. 4, the metal of thetongue shown above the recess might be removed and the full thickness ofthe plate C extended over the portion of the tongue eX- tending beneaththe plate, Fig. 7, or it might be otherwise constructed, the essentialfeature being to have a portion of the plate C extend over a portion oftongue T so that it shall exert a clamping down action thereon. 2o Whilethe drawings show the switch piece made in one integral piece it will beseen that it might be constructed of rails of rolled steel cut andfitted together without departing from my invention. Fig. 8 shows such 25 construction, R', R being the rolled rails and F a cast metal chock orfiller having the boss B for the tongue pin and adapted to support theplate C. The rails R R are riveted or similarly secured to this chock Fas shown.

I-Iaving thus fully described my invention, what I claim, and desire toprotect by Letters Patent, is-

1. In a railway tongue switch in combina tion with the main frame oftheswitch,apiv oted tongue havingatrack surface thereupon adapted tosupport the car wheel; a track surface formed on the frame of the switchand abutting the pivoted end of the tongue and forming a continuation ofthe surface 4o thereupon, and a holding-downplate engaging the pivotedend of the tongue and lying in a pocket adjacent to the aforesaid tracksurface upon the switch frame, said plate being secured to the frame ofthe switch.

2. In a railway tongue switch, a switch frame having a pocket; a tonguepivoted in said pocket, said tongue having upon it a track surface; atrack surface formed upon the switch frame, abutting and forming acontinuation of that upon the tongue so that 5o a car wheel may passdirectly from one to the other, and a plate adapted to engage and holddown the pivoted end of the tongue, said plate being secured to theframe of the switch.

3. In a railway tongue switch, in combination with the frame of theswitch, a tongue pivoted therein; a holding-down plate overlapping thepivoted end of the tongue; a socket in the frame; a nut in the socket,and a bolt passing through the holding-down plate, engaging the nut andadapted to secure the plate in place.

4. In a railway tongue switch, in combination with the frame of theswitch, a tongue pivoted in said frame; a track surface upon the tonguethroughout its length; arecess in the pivoted end adjacent to, but notextending into the track surface; a continuation of said track surfaceon the frame of the switch and abutting the tongue, and a plate enter-7o ing the recess in the tongue and lying adjacent to the track surfaceon the frame, said plate being secured to the frame by a bolty passingthrough the plate and the frame.

In testimony whereof I have affixed my signature in presence of twowitnesses.

HENRY OSIIEA.
